Answer:

x = 72°

y = 36°

Step-by-step explanation:

from the figure we understand that it is an isosceles triangle, the angles at the base are the same, so they are two angles of 72 °

find y

180 - 72 - 72 = 36
  • Here, the two opposite sides of the triangle are equal.
  • So, the triangle is an isosceles triangle.
  • We know, in an isosceles triangle, the angles opposite to the equal sides are same.
  • Here, x° = 72°
  • Therefore, x = 72.
  • We know, sum of all angles of a triangle is 180°.
  • y° + 72° + 72° = 180°
  • or, y° + 144° = 180°
  • or, y° = 180° - 144°
  • or, y = 36

Answer:

x = 72.

y = 36.
